The best way to receive a large B2B payment is, in most cases, a domestic wire or a high-limit instant payment when both businesses bank in the same country, and an international wire or an onchain payment in a dollar stablecoin when they do not. "Best" depends on six things: the amount, how urgent the money is, whether the payment crosses a border, whether it can be reversed after it arrives, what the payer's treasury is able to send, and what the route costs.
A large payment here means five to seven figures from another business: a deposit on equipment, a project fee, a stock order, the price of a company asset. At that size, what decides is rarely the fee: it is whether the money is truly yours when you release the goods or sign, and whether the payer's bank and your bank will both let the amount through on the day you need it.
This article compares seven routes on the same criteria: a domestic wire, a batch credit transfer such as ACH, an instant payment scheme, an international wire, a cheque, a card, and an onchain payment in a dollar stablecoin. Network rules quoted below come from the operators' own publications, with their dates; banks set their own limits and fees inside those rules. This is general information, not legal or financial advice.
Network-level limits published by each network's operator or rulebook owner. A bank may apply a lower limit to its own customers.
What does the best way to receive a large B2B payment depend on?
The best way to receive a large B2B payment depends on six criteria: amount, urgency, domestic or cross-border, reversibility, what the payer can send, and cost. Fix them in that order before you choose a route, because the first four remove options and the last two choose among what is left.
Amount. Every route has a ceiling somewhere: in the network's rules, in the payer's bank, in the payer's own approval policy, or in your account's normal activity.
Urgency. What counts is when you can use the money, not when the payer presses send.
Domestic or cross-border. Domestic schemes do not reach foreign accounts. Once a border is involved, the choice narrows to an international wire, a local collection account in the payer's country, a card, or an onchain payment.
Reversibility. Some payments are final when they reach you, some can be pulled back for a few days for defined errors, and some can be disputed long after the sale.
What the payer's treasury can send. The payer has approved payment methods, daily limits, signatories and cut-off times. Many corporate treasuries cannot send from a wallet at all, and some cap instant payments well below the network limit.
Cost. Cost includes the fee you see, the amount deducted on the way, any currency conversion, and the value of the days you wait.
How do the main routes compare on speed, finality and amount?
A domestic wire and an instant payment give the receiver final funds the same day; a batch transfer is cheap but slower and can be reversed for a few days; a cheque and a card are the two routes where money you can see may still be taken back. The first table covers the criteria that protect the receiver.
| Route | When the receiver has the money | Can it be taken back? | Amount ceiling |
|---|---|---|---|
| Domestic wire | Same business day, inside the system's hours | Final once settled; recovery needs the receiver's consent or a legal process | No network ceiling published; the payer's bank sets one |
| ACH or other batch credit | Same day to a few business days | Reversible for defined errors within a short window | Same Day ACH capped; standard batches limited by the banks |
| Instant payment | Seconds, every day of the year | Final once settled | Network cap in some schemes, bank caps in all |
| International wire | Same day to several business days | Final once credited; a recall needs the receiver's consent | Set by the banks involved |
| Cheque | After the bank's hold | Can be returned unpaid after deposit | None in the instrument; holds grow with size |
| Card | A few days after the sale | Open to a dispute by the cardholder long after the sale | The card's credit limit and the processor's cap |
| Onchain dollar stablecoin | Minutes, every day of the year | Final once the block is finalized | None in the network |
Two points in that table deserve precision. The Federal Reserve Board describes Fedwire, the United States wire system, as a real-time gross settlement system whose transfers are "immediate, final, and irrevocable once processed". And Nacha's rules allow the sender of an ACH credit to reverse it only for listed errors (a duplicate entry, an incorrect receiver, an incorrect amount or a wrong date), with the reversal reaching the receiving bank within five banking days of the settlement date of the erroneous entry. A reversal sent because the sender failed to fund the payment is improper under those rules. For a seller, that makes an ACH credit safe in practice but not final on the day it lands.
The second table compares the same routes on what they ask of the payer and what they cost.
| Route | Works across borders? | What the payer needs | Shape of the cost |
|---|---|---|---|
| Domestic wire | No | Wire access and enough daily limit | Flat fee on each side |
| ACH or other batch credit | No | A business bank account | Very low flat fee |
| Instant payment | No, with regional exceptions such as the euro area | A bank that sends on the scheme at this amount | Low flat fee |
| International wire | Yes | Your full bank details and currency | Flat fees, deductions on the way, conversion margin |
| Cheque | Rarely practical | A chequebook and a signatory | No fee, but days without the funds |
| Card | Yes | A card with enough available credit | Percentage of the amount |
| Onchain dollar stablecoin | Yes | A wallet, the tokens and an internal policy that allows it | Small network fee; conversion if you want bank dollars |
What limits apply to ACH and instant payments on a large amount?
The network limits that matter for a large payment are $1 million per payment on Same Day ACH, $10 million per transaction on the two United States instant payment networks, £1 million on the United Kingdom's Faster Payment System, and no scheme-level maximum on euro instant credit transfers.
| Scheme | Network-level limit per payment | Source and date |
|---|---|---|
| Same Day ACH (United States) | $1 million | Nacha rule, effective March 18, 2022 |
| FedNow Service (United States) | $10 million for customer credit transfers | Federal Reserve notice of November 12, 2025 |
| RTP network (United States) | $10 million | The Clearing House, network page read in October 2026 |
| Faster Payment System (United Kingdom) | £1 million | The scheme operator's page, read in October 2026 |
| SEPA Instant Credit Transfer (euro area) | No maximum at scheme level | European Payments Council rulebook in effect since October 5, 2025 |
Three cautions apply to every row. First, a network limit is a ceiling, not a promise: the Federal Reserve's notice says participants may use the maximum or set lower limits, the operator of the Faster Payment System notes that individual banks and building societies apply their own transaction limits, and the European Payments Council says payment service providers may still set theirs. Ask the payer what its bank allows on that scheme for a business account, at this amount.
Second, an instant payment needs both banks on the scheme: if either is not a participant, or receives but does not send, the route does not exist for this payment.
Third, according to Nacha, a Same Day ACH entry above $1 million is not rejected: it is processed for next-day settlement in the next available window. Above the cap, ask for a wire.
Wires have no comparable published ceiling, but they keep hours. The Federal Reserve Board states that the Fedwire business day begins at 9:00 in the evening Eastern Time on the preceding calendar day and ends at 7:00 in the evening, Monday through Friday, excluding designated holidays. Each bank closes its own wire desk earlier than the system does, and that cut-off is the one the payer must meet.
When does an international wire or an onchain payment make sense?
An international wire makes sense when the payer is abroad and its treasury pays from a bank account, which is the normal case; an onchain payment in a dollar stablecoin makes sense when both businesses are already equipped to send and receive one and need the money to move outside banking hours.
An international wire travels as a payment message from the payer's bank to yours, often through one or more correspondent banks, each of which screens the payment and may deduct a fee. The amount that arrives can therefore be lower than the amount sent, and the delay depends on the currencies, the countries and the checks along the chain. The article on this blog about the best way to send a large international payment covers the sender's side in detail. For the receiver, three things reduce friction: give complete details (account name exactly as registered, account number or IBAN, your bank's identifier code and any intermediary bank your bank specifies), invoice in the currency of the account you want credited, and state in the contract who bears the bank charges.
An onchain payment in a dollar stablecoin moves from the payer's wallet to yours in one transaction recorded on a public network. On Ethereum, the documentation published by the Ethereum Foundation explains that time is divided into slots of 12 seconds and epochs of 32 slots, and that a checkpoint becomes finalized once validators holding at least two-thirds of the staked ether have voted for it and for the checkpoint after it. Two epochs last 768 seconds, so finality typically comes about 12.8 minutes after the payment is included in a block, on any day and at any hour.
The limits of the onchain route are practical, not technical. The payer must hold or buy the tokens and be allowed by its own policy to pay that way. You must control the receiving wallet properly, know which network and which token contract you are accepting, and record the payment in your books. If you want dollars in a bank account afterwards, you add a conversion step with its own fee, timing and bank review. And a stablecoin is a claim on its issuer, so the choice of token is a credit decision.
Why are a cheque and a card the weakest routes for a large amount?
A cheque and a card are the weakest routes for a large B2B payment because both leave the receiver exposed after the money appears in the account: a cheque can be returned unpaid, and a card payment can be disputed.
For the receiver of a cheque, the deposit is a claim to be collected, not money. In the United States, Regulation CC lets a bank extend its hold on the part of a day's cheque deposits that exceeds $6,725, and on any cheque it has reasonable cause to believe is uncollectible; the regulation treats an extension of five business days as reasonable for most cheques and allows longer where the bank can justify it. Availability is also not finality: a cheque can come back unpaid after the bank has released the funds, and the bank then debits your account.
A card suits a payer who wants the credit period or the rewards, and it reaches across borders without bank details changing hands. Against that stand three limits at high amounts: the percentage fee, the payer's credit limit and the processor's own cap, and the cardholder's right under card scheme rules to dispute a charge well after the sale. A card remains a fair choice for a deposit or a small first order.
What happens at your bank when an unusually large payment arrives?
When an unusually large payment arrives, your bank compares it with the normal activity on your account and may review it before or after crediting it. This blog's article on collecting a large payment without triggering a bank hold explains why reviews happen and how long they last. The review is the bank doing its job under anti-money-laundering rules, and the receiver can shorten it by speaking first.
In the United States, Regulation CC requires a bank to make the funds of an electronic payment, such as a wire or an ACH credit, available no later than the business day after the banking day on which the bank received it. That rule governs availability on a normal payment; it does not stop a bank from asking questions about a transaction that does not fit the account.
Prepare the bank a few days ahead:
- Tell your relationship manager or the business desk the expected amount, the date, the route and the payer's legal name and country.
- Have the contract, the invoice and, where relevant, proof of what was sold ready to send the same hour they are asked for.
- Say what you will do with the money next. A large incoming payment followed at once by a large outgoing one is the pattern most likely to raise questions.
- Check that the account can receive this route and this currency, and ask for the cut-off time for same-day credit.
How do you give payment instructions safely?
Give payment instructions safely by sending them once, in a signed document, and by having the payer confirm them through a second channel that was established before the invoice existed. The control is aimed at one risk: a payer who receives altered bank details and sends a final payment to an account that is not yours.
The FBI's Internet Crime Complaint Center recorded 21,442 complaints of business email compromise in 2024, with reported losses close to $2.8 billion. A one-off payment between two businesses that rarely pay each other is where a changed instruction goes unnoticed, and the final routes that suit the receiver are the ones where a misdirected payment is hardest to recover.
- Put the details in the contractWrite the account name, the bank details or the wallet address and network, and the currency into the signed agreement or a signed schedule, not only into an email.
- Agree the confirmation channel in advanceName one person on each side and a telephone number exchanged at signing. State in writing that any change of details is invalid unless confirmed by that person on that number.
- Have the payer call back before sendingThe payer calls the agreed number, not a number found in the invoice email, and reads back the last digits of the account or the first and last characters of the address.
- Decide on a test paymentFor a first payment to new details, a small transfer confirmed on your side proves the destination. This blog's article on test payments covers when it helps and when it does not.
- Never change details mid-deal by emailIf your account genuinely changes, repeat the whole sequence, starting with a signed amendment.
How do you confirm receipt and finality before you release goods or sign?
Confirm receipt and finality by checking the money in your own account or wallet yourself, and by knowing for that route what "final" means, before you release goods, hand over documents or sign. A document supplied by the payer is evidence that a payment was ordered, not that you have been paid.
For a wire or an instant payment, the check is the credit on your account for the full amount, seen in your own banking session. For a batch transfer, it is the settled credit, not a pending entry, and the cautious receiver waits out the reversal window. For a cheque, it is your bank's confirmation that the cheque has been paid, not that the funds are available. For a card, it is the payout to your bank, knowing the dispute right outlasts it. For an onchain payment, it is the transaction on a public explorer: your address, the right token contract, the full amount, in a finalized block.
The article on this blog comparing instant settlement with a bank wire sets out the difference between a payment that is credited and one that is settled. The practical rule is short: a screenshot, a remittance advice, a wire confirmation number or a transaction link sent by the payer does not replace your own check.
What does each route cost on $50,000, $500,000 and $5 million?
On illustrative fees, a wire, an ACH credit and an instant payment cost the receiver a flat $1 to $15 whatever the amount, while a card costs $145,000.30 on $5 million and a converted international wire $25,040. The table is a worked example: every fee in it is an assumption chosen to show how each cost behaves as the amount grows, not a quote from any bank or provider.
Assumptions: domestic wire, a $15 incoming fee. ACH credit and instant payment, a $1 receiving fee each. International wire, a $15 incoming fee, $25 deducted on the way and a 0.50% margin on converting the amount into your currency. Cheque, no fee, but seven calendar days without the funds, valued at a cost of funds of 5% a year. Card, 2.9% of the amount plus $0.30. Onchain dollar stablecoin, the network fee paid by the sender, then 0.10% to convert into bank dollars plus a $25 outgoing wire to your account.
| Route | On $50,000 | On $500,000 | On $5,000,000 |
|---|---|---|---|
| Domestic wire | $15.00 | $15.00 | $15.00 |
| ACH credit | $1.00 | $1.00 | $1.00 |
| Instant payment | $1.00 | $1.00 | $1.00 |
| International wire, converted | $290.00 | $2,540.00 | $25,040.00 |
| Cheque, cost of waiting | $47.95 | $479.45 | $4,794.52 |
| Card | $1,450.30 | $14,500.30 | $145,000.30 |
| Onchain stablecoin, converted | $75.00 | $525.00 | $5,025.00 |
Flat-fee routes become negligible as the amount grows: $15 is 0.03% of $50,000. Percentage routes do the opposite: the card fee on $500,000 is $14,485.30 more than the wire fee, which is why a contract for a large amount either excludes cards or prices them in.
The international wire's cost is almost all conversion: on $500,000, $2,500 of the $2,540 is the margin, and it disappears if you invoice in the currency of an account you already hold. The stablecoin's cost is likewise the conversion step: a receiver who keeps the dollars onchain to pay its own suppliers bears none of the $525.
What if the large payment has to be shared among several parties?
When one large payment has to be shared among several parties, the receiver either collects the whole amount and pays the others afterwards, or uses an arrangement that pays each party directly from the single payment. The first is the default: the money lands in one account, and each onward transfer adds its own limit, cut-off, fee and bank review. Where the parties need an independent party to hold the money until conditions are met, an escrow or settlement agent does that job, and it is a different job from moving money.
Where there is nothing to hold and the shares are simply fixed, a payment router is another option. Shaka is one: each party's share is agreed, and can be signed by each recipient, before the client pays; the client pays once; every party is paid at the same moment, in one transaction, and the payment is final. Shaka routes the payment and never holds the funds, and a deal has at most 20 recipients. It is an onchain route, so the limits described above apply: the payer must be able to pay onchain, and it does not fit a payment that must be held pending a condition or one where the payer can only send a wire.
How do you decide which route to ask for?
Decide by elimination: remove the routes the payer cannot use, then the routes that cannot carry the amount, then the routes that are not final by the time you must release, and choose the cheapest of what remains. Run the questions in this order with the payer's finance contact.
- Is the payer in the same country and currency as your account? If yes, domestic routes are open. If no, go to question 5.
- What can the payer's treasury send at this amount: a wire, an instant payment, a batch transfer? Ask for its bank's limit per payment and per day, and its cut-off time.
- Must you release goods or sign the same day? If yes, ask for a wire inside banking hours or an instant payment if both banks support the amount. If you have several days, a batch transfer is acceptable, and you release after settlement.
- Is the amount above an instant or same-day cap? Ask for a wire.
- Cross-border: do you hold an account in the payer's currency or country? If yes, the payer can pay it locally and you choose when to convert. If no, ask for an international wire, state who bears the charges, and allow several business days.
- Are both sides equipped and permitted to settle in a dollar stablecoin, and does timing outside banking hours matter? If yes, an onchain payment is a candidate; agree the network, the token and the address in the contract.
- Is the payer proposing a cheque or a card? Accept on the understanding that you release only after collected funds for a cheque, and that a card payment carries a fee and a dispute right; for the main amount, propose a transfer.
Then do the three things that apply whatever the route: warn your bank, lock the instructions with an out-of-band confirmation, and write "cleared and final funds" into the release condition.
